What is a FOB Battery?

A FOB (key fob) battery is a small, lithium-ion battery that powers the remote keyless entry system in your car. It allows you to lock and unlock your car doors, open the trunk, and even start the engine without having to insert a key. FOB batteries typically last for several years, but they will eventually need to be replaced.
